Nice work!
Were the fuel line leaks easy to diagnose?

Replaced some fuel lines (between in-line filter and preheater thermostat
and between thermostat and lift pump) and three of six glow plugs -- ran
out of time and patience with the glow plugs. Not bad for starting at 8 pm
and getting done by 11.
A secret if you ever need to change the glow plugs on a 300D with a 603:
Push the cruise control linkage forward when changing #3. Takes the job
from un-doable to easy as pie. Still requires six hands and two lights and
a lot of cursing, but much easier.
My nephew who is training to be a diesel mechanic helped, and actually
participated this time. Badly spoiled by his mother, hard to keep him
motivated, but he stuck to it this time. Still rather fumble fingered and
doesn't think things out, but progress is being made.
Found all the intake manifold bolts just barely finger tight, so torqued
them all down. Car starts better and runs MUCH better, still got a knock
in #6 at idle, probably a bad pressure valve holder seal. Idle is vastly
improved, no more shaking and pounding, so I think much of the running
issues I've had recently were due to air inflitration from those bad
lines. Cracks, rock hard, split on the ends, problem was much worse cold.
I guess I'll find out Thursday morning if it will start sub-zero. If not,
I'll stay home till noon, the TE needs gas line repairs that will require
having a new rubber bit crimped onto a steel line, part is NLA -- it's the
line that the hose from the rear fuel pump attaches to that jumpers to the
rear of the front pump and, I think, has the bleed line from the pressure
regulator/accumulator attached. One inch long piece of rubber hose is
going bad. Later models all have banjo fittings on the pumps, someone must
have had a better idea, eh? At any rate, I'll pull it off soon and take it
to the hydraulic place my brother found who made the hose from the rear to
front pump for us after two replacements failed in a couple weeks. 200 PSI
rated fuel line, should last a while, I think.
Next weekend I'll put the other rear wheel bearing in the TE and hopefully
shocks in the rear of the diesel -- be nice to have TO operating cars since
I need to make a trip to Chicago on the 20th.
